The problem is that gun control is not really focused at controlling criminals; it is focused at controlling law abiding citizens. When LACs have no recourse to self defense, they must become dependent on outside means of protection. The government wants us dependent on them; wants us to need them.
IMO, gun control will not come through legislation, gun bans or confiscation. The most effective way to control guns is to make it so prohibitively expensive (along with the general inflation of the cost of living) that one must choose between ammo and guns or shelter and food. We will still "have" our "rights", (in a manner of speaking) but we won't be able to afford them.
